my buddy has a galaxy s4 active from at&t he wants to sell. it was on contract and he canceled his service and has a balance due.
if i buy the phone from him can i just take it to T-mobile and buy a plan/switch out sim cards and be able to use it? or does he have to
resolve everything with at&t first?
He would need to get everything resolved and request an unlock from AT&T. Depending on your area the best you'll get is EDGE speeds. If your area is refarmed you can get HSPA+. I am unsure of LTE if the phone supports AWS spectrum.
He needs to resolve everything with AT&T and request an sim unlock
code before he cancels before you can use it with Tmobile.
It supports LTE on the AWS band.
